Hibernate之deleted object would be re-saved by casc

在Hibernate中，删除存在关联关系的一个对象时，会出现 org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations)这个异常

解决方案如下：

方法1 删除Set方的cascade

方法2 解决关联关系后，再删除 :

//移除关联关系

webSite.getTemplates().remove(template);

//删除

templateService.delete(template);

方法3 在many-to-one方增加cascade 但值不能是none
